The man who died after shooting and killing a deputy and K9 officer has been identified.
On Monday night, deputies tried pulling over Robert Stephen Calderon, who was on parole, at Arden Way near Morse Avenue. He stopped, then drove off, prompting a chase. Calderon eventually crashed his car near the horse track at Cal Expo. Deputies shot out Calderon's back window before deploying a K9, but Calderon opened fire, killing K9 Riley and Deputy Adam Gibson. Deputies returned fire and Calderon died from the shooting.
